Mineralogical wealth of the Geopark is associated primarily with magmatic rocks, either Paleozoic melaphyres, or Cenozoic basalts. Since very early times, people have been collecting and processing agates and other quartz varieties, mining pyropes, iron ores or gold. Mineralizing fluids should be also credited for the preservation of some fossils.

Precious stones

The areas of Turnov and Nová Paka have been renowned for the finds of precious stones (semi-precious stones) since medieval times. Their source rocks are Permian basalts (paleobasalts), often displaying amygdaloidal (melaphyre) structure, i.e., containing numerous vesicles.

Besides semi-precious stones, many other interesting minerals can be found in the Geopark territory.
